A sports racket having a head including a frame within which is strung a plurality of string elements interconnected in such a manner to provide substantially concave ball-engaging surfaces on each face of the racket head.
A stringing arrangement for a sports racket which compensates for twisting of the racket in the hand of the user when a ball is hit by areas of the racket to either side of a substantially flat middle region which extends from the heel to the tip of the racket frame. The stringing arrangement presents spaced string areas to opposite faces of the racket from the middle region outwardly to the sides of the racket frame. These spaced string areas become progressively farther from the plane of the substantially flat middle region from said middle region to the sides of the frame.
The racket head frame is provided with a predetermined number of recess cuts, each of which is used to receive therein a stringing tube of stringing element of plastic material. The stringing element has two shoulders for use in shielding both stringing tube and the surface of the racket head frame. Two stringing tubes located respectively and correspondingly on the two shoulders are coupled by means of a connection portion, which serves to shield both the string and the side surface of the racket head frame.
Racket with the racket head built up by crossing strings fastened to a frame, especially a tennis racket. Both the main surfaces of the racket head have a concave profile over at least a portion of each surface in at least one dimension of the racket head. The concave profile is provided by distance pieces or spaceers of different thicknesses inserted between the strings at various crossing points.
A racket with a stringing pattern utilizing at least one string has two fully interwoven string regions and a partially interwoven string region interposed between the two fully interwoven string regions. At the boundaries between the regions elastomeric anchoring tubes with the strings passing therethrough space the cross strings from the main strings so that spin is easily imparted to a ball struck by the racket and balls with spin are easily received and returned. In the partially interwoven region, the string is strung in three planes. A racket stringing kit provides at least one string and at least one tubular anchor having an outer diameter sufficiently greater than the string diameter to space the main strings from the cross strings in the partially interwoven string region. A method of completing the string pattern comprises inserting the string through a hole in the racket head and inserting the string through a first anchoring tube. The string is then inserted through second and third holes in the racket head and following that a second anchoring tube. After the second anchoring tube the string is inserted through a fourth hole in the racket head and knots are tied at the end of the string.
A sports racket having a head including a first frame within which is strung plural string elements interconnected to form a ball-engaging surface on each face of the racket, further comprises a second frame formed with a hand grip and first and second frame arms projecting outward therefrom. Each first and second frame arm has two welded points of connection with the first frame located respectively at upper and lower portions of the racket head. Upon impact of a ball with the string surface, impact force is transmitted to the second frame through the points of connection, permitting the racket head to flex between the points of connection so that the string surface remains generally parallel to the hand grip for improved controllability of the ball.
